Hi Jayce,

seen you have HTC one X and Samsung S3, would you mind post comparison for these 2 unit. I mean the feeling of both phone not the spec wise (which can google around). something like using the 1X/S3 in pocket, how it feel? or use for long hour, does it feel hot and uncomfortable? and the handling as in malaysia hand, how does it feel when holding it? 1 hand or 2 hand have to be use? when driving, does it feel ok?(you know what mean as in malaysian, we do write/read sms when driving or make call)

Hi Jayce
After rooting my s3 the battery drains fast without heavy use
please any idea to solve that. I will charge today night and the next day evening it has left only about 17% of remaining battery without heavy use.

Hi Jayce, I want to unroot my samsung s3 but when i got to the procedures you presented, it only stucked me for hours on “downloading…. do not turn off target like”. Your video presented like it only takes seconds to that process then how come mine takes more time. Do you have any idea what went wrong? Thanks

Hi thanks for your reply. I thought, my device has already been bricked (not sure). My phone won’t boot up anymore, all I can see is a splash logo of samsung then the language screen wherein you set up your device (same screen when you unbox your device the first time you open it as I was able to wipe data/factory reset it thru recovery mode but still nothing happens). When it gets to set up language screen, my phone suddenly hangs & can’t do anything about it.) I triend every possible means, flashing & unrooot using SGS3 toolkit via odin but still nothing happens. A bit worried though.

I did read it but my phone doesn’t have an installed triangle away apps. Is there a way to download it since i can no longer boot up my device successfully? From the time i turned it on, only a samsung splash logo appeared but after that it stucks to language screen (it’s like setting up the phone for the first time), but whenever i pressed language bar, my phone hangs.

really, thanks i was kind of freaking out by this thing. Anyway, do you have a firmware? ‘was thinking if you could send me a coorect firmware for my phone blg no. IMM86D.I9300XXBLFB.. I bought the phone in the PHilippines but currently I am here in algeria. Here’s my email address vincecabz101@yahoo.com Thanks a lot

I don’t have firmware. Please follow the guide to download from Internet.

Hi jayce,

i have rooted my phone with a build number JZ054K.i9300XXEMA2
and baseband version is i9300DXELK1 . i feel something is not right with my rooting process.. i want to unroot and root once again follow your step by step process.
I also have a siyah kernel.

so can i just unroot using your steps in the video? will the siyah kernel automatically change to stock kernel or is there additional steps to remove the custom kernel?

Im currently having a galaxy s3 and would like to root my phone but I really dont want to lose my 2 years warranty. (Now its 1 and a half years). Im a beginner in these rooting stuff.

hi i used triangle away below is the result is this meant to be like this or should the system status be official straight after the use of triangle away.
ODIN MODE
PRODUCT NAME: GT-I9300
CUSTOM BINARY DOWNLOAD: No
CURRENT BINARY: Samsung Official
SYSTEM STATUS: Custom

im at the stage Device status should be MODIFIED jay.. but mine was in custom and not appearing that should be SCANNING… right? how to made it like that.. i follow the video step by step with your text guide too

yMt

and when i repeatingly press the build number i enabled the developer option

i mean in the first part jay… when going to the ABOUT DEVICE of my samsung gs3, the device status of mine is CUSTOM… but in your video after doing some step it should be SCANNING then it became MODIFIED…

how can i fix that CUSTOME device status… it doesnt do SCANNING that it should be to become MODIFIED.. to proceed using the Triangle away app
